The recovering 21-year-old singer, who was hospitalized for a week following an "extreme allergic reaction" to a prescription antibiotic, shared several pics on Instagram today that indicated she's feeling much better.

First off, she has her appetite back.

In a selfie the Bangerz artist is munching on a pancake while wearing a T-shirt with an illustration of two little kids on it in which one is conspiratorially telling the other, "DON'T LET THOSE MOTHERF--KERS KILL OUR VIBE."

Her next pic shows her sprawled in bed, fully covered in some sort of quilted dressing gown, while Wayne Coyne of The Flaming Lips peers through the viewfinder of a camera set up on a tripod next to the bed.

At times likes these, it's fortuitous that Coyne's Instagram handle is "waynewontpostpicsofnakedwomen."

Cyrus pal @katyweaver is also tagged in the latter snapshot.

Miley and the Flaming Lips did collaborate in the studio recently, for a cover of The Beatles' "A Day in the Life" and other Fab Four tunes, and both Coyne and fellow Lip Steven Drozd joined Miley onstage to play "Yoshimi Battles The Pink Robots Part 1" at L.A.'s Staples Center in February.

So Coyne taking pics of Miley in bed isn't that weird. They're pals. (In encouraging fans to buy their Bonnaroo tickets, Coyne also posted a pic from that night at Staples Center with Miley on his own Instagram page today.)

The next pic shows her in bed, still in the dressing gown and fiddling with either her phone or a tablet that's casting a bright neon glow across her face and forming a big shadow of her head on the wall behind her amid a psychedelic sunburst.

Groovy!

But it's good to see that Miley is feeling better. A source close to her told E! News yesterday, in confirming that Miley was out of the hospital, that her upcoming European tour schedule has not changed. If all goes according to plan, she'll be taking the stage May 2 in Amsterdam.
